nginx: [emerg] unknown directive "ssl" in /usr/local/nginx/conf/vhost/ssl.conf:7

故障：

/usr/local/nginx/sbin/nginx -t检查nginx语法时，出现nginx: [emerg] unknown directive "ssl" in /usr/local/nginx/conf/vhost/ssl.conf:7

解决方案：

1.到解压的nginx目录下

./configure --with-http_ssl_module

2.当执行上面语句，出现./configure: error: SSL modules require the OpenSSL library.

用 yum -y install openssl openssl-devel

再执行./configure

3.从新执行./configure --with-http_ssl_module

make ，切记不能make install 会覆盖。

4.把原来nginx备份

cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak

5.把新的nginx覆盖旧的

cp objs/nginx /usr/local/nginx/sbin/nginx

出现错误时cp: cannot create regular file ‘/usr/local/nginx/sbin/nginx’: Text file busy

6.用cp -rfp objs/nginx /usr/local/nginx/sbin/nginx解决

7.测试nginx是否正确

/usr/local/nginx/sbin/nginx -t

（nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful）

8.重启nginx

/usr/local/nginx/sbin/nginx -s reload
